Git would have been helpful to me in my very first intro to programming course. It fixes those situations of: "arg, I changed one thing - it no longer works, and I'm not even sure anymore what that one thing was!"

Second, a successful CS grad has hopefully written at least something that is at least 2000 lines long. Doing that without VCS of any kind is not impressive, it is obtuse. That is a strong no hire signal imo.
